concern: 1

Beit known that I, JAMES MILEs AKERS, a

' citizen of the United States, residing at Ga s,

l transportation, with the 1n the county of Moultrie, and State of I linois, have invented a new and usefuFPneumat1c Grain-Conveyer, of which the followin is a specification. his invention relates to pneumatic grainconvcyers, and especially to devices of this class whereby grain, shelled corn, and the like may be. loaded into manual labor involved in throwing the material toward the ends of such cars. 3-

The invention has forits object to resent an apparatus of this character whic shall 7 possess supcrioradvantages in point of simplicity, durability, nd general efficiency; and with these and other ends in view, which Willreadily appear as the nature of the invention is better understood, the same conillustrated a slmple and preferred form of em sists in the improved. construction and novel arrangement andcombination of parts,which will be hereinafter fully described, and particularly pointed out inthe claims.

In the accompanying drawings has been bodiment of the invention, it being, however, understood that no limitation is' necessarily made to the precise structural details therein exhibited, but that the right is reserved to any changes, alterations, and modifications to which recourse may be had within the scope of the invention and Without departing from the spirit or sacrificing the efliciency of In said drawings, Figure 1 is a sectional elevation of a pneumatic grain-conveying a paratus constructed in accordance with t e principle of the invention. Fig. 2 is a top plan view of the same.

Oorres onding parts in both figures are indicated throughout by similar characters of reference.

The improved device includes a blower the casing of which, 1, is provided in the manner with bearings for a shaitv2,

usual upon which is mounted a hub 3, havin radiating arms 4,-carrying fan-blades 5 o ordinary construction. he blower takes air through the eyes in the sides of the casing and dischar es throu h an outlet 6.

Su porte upon 51c part of the casing which constitutes the outlet portion 6 is an PNEUMATIC GRAlN -CONVEYER.

It will be observed that the valve or damper 15 may be adjustedandseeured in vari-,- ous positions so as to regulate and positively control the quantity of material permitted to ass through the s out or chute 12 into the eeder-casing and t at the tpassage of material through said s out may e cut off entirely Mihen desired. is-is obviously importantin order-nob to overfeed the deviee-orsu ply ;-it-;vvithmaterial, beyond theeapacity d the ;fan.

1 aving thus described the invention, what is claimed is 1. In a pneumatic conveyor, a fan-casing illaving a;d1sehar e-sp out, an auxiliary casing constituting a "coder-easing located above and communicating with the .dischar espout, a feed-spout communicating with t e feedeneasing, and a paddle-wheel supported for rotation within, and having wings or paddles extending to the walls of said-feeder-easing-to-preventthe assage ofmaterial between said-Wings'an the walls of: the casing.

2. Ina pneumatie eonveyer, a fan-easing having a dls'charge-spout, an auxiliary casing constituting afeder-easing located adjacent to and communicating with a dischargespqut a paddle-wheel supported for rotation -tvithin the auxiliary casing, a feed out eonneete'd with, thelattena valve or ampen-in the feed s out, and means for operating said valve or amper and for securing. it-at various adjustments.
